The Russian Investigative Committee said Monday it had launched criminal cases into the shelling of civilians in Donbass this month by Ukrainian forces.

Ukrainian Armed Forces and National Guard members conducted precision artillery shelling of civilian infrastructure in the Donetsk region on March 11-23, Sputnik quoted the committee’s spokeswoman, Svetlana Petrenko as saying.

“A civilian died, and nine people were injured,” Petrenko said of the shelling that damaged or destroyed over 50 pieces of civilian infrastructure, including houses.

The case was opened under the Russian Criminal Code’s article on the use of means and methods of warfare banned by Russia’s international treaty in a military conflict.

Also, the Committee launched criminal cases against a Ukrainian second lieutenant and a colonel from the 93rd Mechanized Brigade, who are suspected of carrying out heavy shelling of civilian infrastructure from August-December 2015.
